We're assuming good input anyway, so we can shave another off... 

sub num2ord {
  local $_ = shift;
#          1        2         3         4
# 123456789012346789012345678901234567890
  $_.(qw(0 st nd rd)[/1?.$/g]||th)
}

Which drops us to 33.

    One bareword hardly seems enough:

    sub num2ord {
  local $_ = shift;
#          1        2         3         4
# 123456789012346789012345678901234567890
  $_.((0,st,nd,rd)[/1?.$/g]||th)
}

    Update: oops, typo: too many parens at start.

      Those ** should be 456, not 46 - that appears to have been copied by everyone ;)

      Also, one extra character can be removed:
      sub num2ord {
  local $_ = shift;
#          1         2         3
# 123456789012345678901234567890
  $_.=(0,st,nd,rd)[/1?.$/g]||th
}
